What Jets are you using?
Does anyone know if you can dyno your own bike on the street using Air Fuel Meter and wheel sensor in some app

I need jets for aus 99 mc22 with no air filter and no exhaust muffler

Sure you can tune with wideband O2-sensor. Best to get one with datalogging of RPM so you can take time later to analyse data in 100rpm increments. Much more precise and safe rather than trying to stare at AFR gauge while doing WOT runs @ 150+ and watching out for traffic at same time. I really like these all-digital units.

Most likely you'll have to downsize main jets 1-2 sizes. Max power is made at around 13.5:1 AFR. This is too close to edge of detonation and self-destruction. So no OEM manufacturer dares runs this lean. They prefer to have safety margin in case you get bad gas on super-hot day. But that leaves lots of power on table.
